I now realize I've been tackling Candida overgrowth issues my whole life. I didn't know what I was, but in the end I had 24 symptoms!!! There was acne, bloating, cold feet, whatever.
All the books talk about causes of Candida - usually bad diet, too much sugar, dairy, Antibiotics - but I don't think so any more. I think these are triggers only. Candida thrives on them. But the real underlying cause I think is deeper - it's emotional, psychological, and so on.
